## What is Marcus Books?

Teach patients about pain management using augmented reality experiences!

Patient education about pain management has been shown to reduce opioid use and mitigate risk of acquiring Substance Abuse Disorder, but it can be difficult to create engaging educational materials for pediatric patients. 

We partnered with C.S. Mott Children’s Hospital to create Thump! Ouch! Marcus Gets Hurt, an effective and fun tool to educate even the youngest patient about pain management safety.
